Summary0006433: Writing a test to simulate an attack on the tcp communicator KX to test the replay protection.
DescriptionThere is a replay protection for the tcp communicator implemented using a nonce send together with the ephemeral key. If the nonce is not send back the queue will be destroyed. To test this there has to be a peer not sending back the nonce within the defined limits. One possible way to do this is to build a variant of the tcp communicator to be used for the second peer in the communicator test. This second build changes some parts of the communicator code to send a wrong challenge or none at all.
